Substitute Part Grouping Explanation

Substitute parts for the Dialight 5614101081 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key criteria:

• Electrical Specifications: Voltage rating (1.9V), current rating (20mA), and brightness output (5mcd) must be identical
• Optical Characteristics: Color (red), wavelength peak (635nm), lens type (diffused), viewing angle (100°), and configuration (single) must match exactly
• Mechanical Specifications: Lens dimensions (7.00mm x 2.50mm), lens style (rectangle with flat top), and mounting type (through hole) must be identical
• Environmental Compliance: Moisture sensitivity level (MSL 1) must be maintained

The substitute parts identified—5614101081F and 5614101055F—meet all these criteria while offering the advantage of active product status and improved RoHS3 compliance compared to the obsolete main part.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts—5614101081F and 5614101055F—are direct functional equivalents to the obsolete 5614101081. Selection between these alternatives should be based on the following factors:

5614101081F: This part maintains the closest designation alignment to the original part number while offering active product status. It is suitable for applications requiring minimal design documentation changes and direct part number traceability.

5614101055F: This part provides an alternative within the same Dialight 561 series with identical electrical and mechanical specifications. It is suitable for applications where part number flexibility exists within procurement systems.

Both substitute parts offer the critical advantage of ROHS3 compliance, addressing regulatory requirements that the obsolete main part does not meet. The active product status of both substitutes ensures long-term availability and supply chain continuity. Packaging is provided in bulk format for both alternatives.

Frequently Asked Questions (FAQ)

Q: Can 5614101081F and 5614101055F be used interchangeably with 5614101081?

A: Yes. Both substitute parts maintain identical electrical specifications (1.9V, 20mA, 5mcd), optical characteristics (red, 635nm, 100° viewing angle, diffused lens), and mechanical dimensions (7.00mm x 2.50mm rectangle with flat top, through-hole mounting). They are direct functional equivalents.

Q: What is the primary reason for substitution?

A: The original part 5614101081 is classified as obsolete. The substitute parts 5614101081F and 5614101055F are active products within the same Dialight 561 series, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between the main part and substitutes?

A: Yes. The main part 5614101081 is RoHS non-compliant, while both substitute parts (5614101081F and 5614101055F) are ROHS3 compliant. Both maintain REACH Unaffected status. If RoHS compliance is required for your application, the substitute parts are necessary.

Q: Do the substitute parts have different packaging?

A: The main part 5614101081 is listed with dash packaging notation, while both substitute parts are supplied in bulk packaging. Confirm bulk packaging compatibility with your procurement and assembly processes.

Q: Are the electrical operating parameters identical?

A: Yes. All three parts operate at 1.9V with 20mA current rating and deliver 5mcd brightness output. No circuit design modifications are required when substituting.

Q: What is the difference between 5614101081F and 5614101055F?

A: Both parts are functionally identical across all provided specifications. The primary difference is the part number designation. Selection between them depends on your procurement system flexibility and documentation requirements.
